Finding if a python datetime has no time information

Question

I want to trap values that are like this (in which there is not 'time info' on the datetime):

datetime.datetime(2009, 4, 6, 0, 0)

Is there a better way to detect these values other than testing hour/minute/second?

if value.hour == 0 and value.minute == 0 and value.second == 0:
     # do stuff

Answer 1

I see nothing wrong with your method, but you could compare it to a 'zeroed' time object.

someDateTime = datetime.datetime(2009, 4, 6, 0, 0)
someDateTime.time() == datetime.time(0)

Answer 2

Another option:

if not (value.hour or value.minute or value.second):
    # do stuff

Answer 3

You would actually need to check microsecond as well. Another option:

NO_TIME = datetime.time(0) # can be stored as constant

if (value.time() == NO_TIME):
   # do stuff

Answer 4

don't neglect that HMS==0 for 1 in 86,400 fully completed time values! depending on what you're doing, that might not be negligible.

Answer 5

The time method works here. Evaluates as boolean false if there's zero'd-out time info.

if not value.time():
    # do stuff
